Narrative:
Misinterpreted gear horn for a stuck stall horn. Had not heard the gear up horn before while being checked out in flight. I have experienced a stuck stall horn before due to turbulence in a similar aircraft and assumed it was the same thing. Contributing factors included exchange of controls on base and before landing check. What can be done to prevent a recurrence is further training in unfamiliar aircraft and learning all systems more thoroughly before flight. Also; exchanging controls earlier on before landing; downwind for example; and increased frequency and quantity of before landing checks.
